TPV is highly vulcanized EPDM EPDM particles dispersed in the continuous polymer elastomer material composed of polypropylene PP phase. The physical properties and function of TPV under normal temperature similar to that of thermoset rubber, show the characteristics of thermoplastics, at high temperatures can be quickly economic and convenient processing molding. TPV thermoplastic dynamic vulcanized EPDM/rubber vulcanized rubber elastomer material by dynamic vulcanization EPDM EPDM for less than 2 micron sized particles dispersed in the polypropylene PP plastic substrate, combine the characteristics of rubber and plastic good together, get excellent comprehensive properties of high performance elastomer material.
